“…The microfauna of the Barstow Konservat Lagerstätte has yielded three-dimensionally preserved insects including diving beetle larvae (Schistomerus californensis), flies (Dasyhelea australis antiqua and Culicoides), mosquitos (Anopheles), midges, thrips and wasps (Hymenoptera), together with abundant fairy shrimps (Anostraca), wolf spiders (Lycosidae), copepods, diatoms (Craticula, Dimidiata, Amphora, Nitzschia and Anomoeoneis) and body fossils and ephippia of zooplankton such as Branchiopoda and Anomopoda (Palmer & Bassett 1954;Palmer, 1957;Park 1995;Belk & Schram 2001;Park & Downing 2001;Miller & Lubkin 2001;Leggitt 2003Leggitt , 2005Leggitt , 2006unpublished data). During the history of the lake, the faunal composition and insect diversity changed significantly, probably due to differences in water chemistry, a shift of the shoreline due to shallowing and increased aridity (Park & Downing 2001).…”

Exceptionally well-preserved specimens of a new cypridid ostracod (Crustacea), Raepula ira sp. nov., are described from palaeolake sediments of the Middle Miocene Barstow Formation of the Mud Hills, southern California. This is only the second occurrence of exceptionally preserved ostracods from the Miocene. Based on ages obtained from associated volcanic tuffs the palaeolake sediments were deposited between 16.3 and 15.8 Ma. The ostracods form one element of a diverse lake community dominated by fairy shrimps, copepods, diatoms, larvae of diving beetles, flies and mosquitoes, and body fossils and ephippia of branchiopods and anomopods. The ostracods are preserved three-dimensionally with their soft anatomy replicated in microcrystalline silica. Sub-micron scale details such as sensory setae are preserved, surpassing the resolution of most other ostracodbearing lagerstätten and allowing their biology to be compared with extant taxa.

“…Both of these collections yielded many well-preserved fossil arthropods. The processing of these nodules continued through the spring of 1954, and in August a preliminary notice of the occurrence was published (Palmer and Bassett, 1954).…”
